I'm sorry but if I was 2 hours late for a work appointment when I was his age I would have had my arse chewed off.
Stupid little manchild needs to grow some balls, grow up and learn to respect his audience. They are paying for his baggy pants, they are paying for the nice watches/ bling.
All that will happen is those young kids who worship him will suddenly think "well if he doesn't care enough about me to turn up on time, why should care about him?
Young girls tend to take things like that VERY personally.
